PS-8-LP
POWERPATH NAC Power Supply
Description
The Wheelock POWERPATH (PS-8-LP) by Eaton is a supervised
remote power supply/battery charger in a low profile cabinet that is
used for supervision and expanded power driving capability of fire
alarm Notification Appliance Circuits (NAC). The PS-8-LP is filtered
and regulated and provides 8 amps of power distributed across 4
outputs.
The power supplies may be connected to any 12V or 24V (FWR
or DC) Fire Alarm Control Panel (FACP) by using a NAC or a “Dry
Contact.” Primary applications include NAC expansion (supports ADA
requirements) and auxiliary power to support system accessories.
This unit provides filtered and regulated 24VDC, up to four (4) Class
“B”, two (2) Class “A”, or two (2) Class “B” and one (1) Class “A”
Notification Appliance Circuits. With the optional plug-in PS-EXP
module the unit supports (8) Class “B” or (4) Class “A” Notification
Appliance Circuits. Additionally, an auxiliary power output of 2.5
Amps (disconnected upon AC power loss or an alarm condition) or
up to 0.240 A of constant power on the PS-8-LP.
The Wheelock power supplies can accommodate 7 AH batteries
inside its lockable chassis. Using an external battery cabinet it can
charge up to 33 AH batteries (pending UL testing). Two FACP NAC
circuits or two “Dry” contact initiating circuits can be connected to
the inputs. These inputs can then be directed to control supervision
and power delivery to any combination of the four (4) outputs. Each
output is rated at 3.0 Amps (Class “B”) or (Class “A”) and can be
programmed to generate a steady or Code 3 temporal horn sound
and a strobe output under alarm condition. Total load for PS-8-LP
NAC circuits must not exceed the power supplies rated output.
The power supplies under non-alarm condition provide independent
supervision for Class “A” and Class “B” FACP NAC circuits. In
the event of circuit trouble, the FACP will be notified via the
POWERPATH steered input (IN1 or IN2). In addition there are two
sets of trouble reporting terminals, one used for AC power loss
reporting and the other for all troubles. The AC power loss reporting,
on the common trouble terminals and on IN1 or IN2, can be delayed
for either 30 seconds or 170 minutes. The AC power loss terminals
will always report the trouble within 1 second after loss of AC
power.
The PS-8-LP power supplies are UL listed under UL Standard 864,
9th Edition to be used with any 24 volt listed regulated notification
appliances. They include the capability to synchronize Wheelock
strobes and horns and to silence the horn signal when horn/strobes
are operating on two wires.
